GILBERT JAMESARNQLD, or EASTBOURNE, ENGLAND WHEEL WITH DETACHABLE RIM.

To all whom it may concern: A

v:Be itV known that l, GILBERT JAMES AR- Non), F. R. C S., a subject of the King'of England7 residing at Eastbourne, England,

have invented certain new and useful Improvements in 'Wheels with Detachable which the following is a specifica- This invention 4relates to' wheels having detachable rims, of the type wherein the rim is gripped` between flanges one of which is I vfast on the wheel and the other is carried by a detachable side-ring. Such rims are usually held by theside-ring being clamped to the `wheelelement by bolts and nuts which exert their securing thrustagainst 'the side-ring at a point which beds iiat against the wheelfelenient. The Sidering is thus made rigid with the wheel-element and if Y the rim is a little small it fails to be properly gripped, Whereas if it is a little large, it f puts great strain upon the bolts and tends to bend them inward or break them. l

l The objectof the 'present invention is to so securethe side-ring that it constitutes a resilient connection between the detachable. rim andthe wheel-element, and. for this pur-l pose the side-ring is made to bedl against.

' the wheelelenient only at its inner edge',

whereas its outer edge beds against the rim,

and the parts are lso p roport'ionedl that the main'body of theside-ring is held free. of the wheel-element. Thel fastening boltsare so positioned as to exert their securing thrust at points between the inner edge of the sidef ring which beds against the wheel rim and the outer edgewhich beds against the letachable rim, and thus the part of the ring which. receives the securing thrust vcan be sprung inunder the action of the, bolts without its being brought forcibly lagainst the .wheel-element; thismiddle portion of the sideering thus affords ajyielding part which makesnthe whole ringfserve as a resilient conl ment;

forms, and in l a wooden felly A is *I 'shown' having alixed flange B on one side of it. Thisiange, which is of, metah is madet in one with a band B1 which extends across the face of the felly and is turned over at B2 on that side of the wheel remote frein the flange B. The inner edge of this turnedover portion B2, thatA is the edge which is nearest the center of the wheel, is outwardly turned at vB3 to provide a laterahrib. -The riin C may be ofI any suitable construction 4and beds on one side againstthe liange B and on the other vside against a flange D forming part' of a detachable sideplate Di. l The side-plate has an inwardly-directed lip D2 on its inner edge'. This 4lip is .made to 4'lie within theeannularrib4 or edge B of the plate B2. Secured to the plate B1 by rivets B4 isa series of'bolts of which .one is shown atBE. These bolts are'shaped to form an angle-piece between the band B1 and its over-turned 4edge B2. The proportions of the rim C and side-ring D1 with its -flange D are such that ,when t e inner edge of the' side-ring D1 is made to bear against the rib' B3 of the Vwheel-element, the main body of the sidelring'is heldcle'ar of the side of the wheeLeleinent, 'that is, of the over-turned portion BZ-of the band B1 which with the felly. constitutesy the- WheeLeIement.

bolts B extend through orifices in that por` I tion of'the side-ring which liesbetween the line of Contactl of Vthe ring withthe'rib BS and the line of contact with the rim C. lt

followstherefore that vthe securing thrust of the nuts B" on thel bolts is exerted against that part eithe side-ring which is not directly supported by fthe wheel-element, and tti-usa ce l*ain,amount of resilience is .pro-- vided 'het Eileen the wheel-element and the 1 ico rim C. It! will be appreciated that ifthe" ring 4l were' allowed to bed itself dat `against the wheel-element, this' "resili'ence would not exist Further, it is found that ifthe inner edgeof the side-ringi is allowed toibear against the wheel-element and the lianged edge D is held away therefromby l around the same as shown y'in the drawing.

I The resilience adordedby the arrangement of the side-ring as described, enables a good grip te' be obtained of the wheel-rim without breakage of the parts.

ln Fig. 2, the same arrangement of sidey l ring E is shown applied to a wheel-element F having no wooden felly, the spokes "F1 being attached direct to the. metal band on which the ixed flange F2 is formed.

ln Fig. 3 the same arrangement of sidering Gis shown applied to a wheel-element l-l, H1 which is similar to that shown in-Fig.

1, but provided with bolts J for securing the side-ring which extend rifrht through the wheel-element.

ln Fig. 4 the invention is shown as applied to a twin-rimmed wheel. rllhe wooden felly K carries a metal band K1 having a fixed side flange K2 and an overturned edge K3 on the opposite side of the wheelhaving a lip K4, all as has been described with reference to Fig. l, except that the band K1 is wide enough to take two rims and their assoelated parts instead of one.' In the middle of the band K1, a split ring L having double flanges L1, L2' is provided, the flanges being turned in toward each other so that the flange L1 eoperates with the flange K2 to receive a detachable rim M and the flange L2 coperates with a flange N on a side-plate N1 to receive a detachable rim O. The' plate N1 is secured to the wheel-element by bolts and nuts P, P1 and made to constitute a resilient connection between the rim O and the wheelelexnent, as has been already described with reference to the side-ring D, l)1 of Fig.` 1.

The central split ring L has its two ends eonnected by means of aibolt L3 whose stem passes through the band K1 on the felly K; The head of the bolt lies -w1th1n the trough formed between the two flanges L?,

L2 and has on its under-side two pins L?- which engage orifices in the ends of the ring and in the band K1. The-head of the bolt thus holds the ends of the ring L together and can itself be clamped tight by the Wingnut L5. The orifices in the band K1 engaged by the pins L4 and the orifice in the felly K through which the stein of the bolt passes, are conveniently slotted in a direction transverseto the eircumferential direction of the wheel, so that a littl side adjustment of the ring L can be alloweu' fin'. It thus follows that when the side ring Ell is bolted up,

which. engage orifices in the bar 4ing provided with a flange one detachable side-ring N1.

To prevent the rims from creeping. relatively to the wheel-element, a transverse bar QA is provided which extends through the flange K2, the flanges L1, L2, and the central ring L and side ring N1, slots being provided in all these members to receive it. rThe rims M and 0 are provided on their inner side with pins l 1 and 01 respectively, Q; the valve-stems R 'also conveniently entend through this bar and of course ent l through the wheel-element aiso,in the us n. manner.

What I claim as my invention vand desire to secure by Letters Patent is l. ln a wheel and detachable rini, the cornbination of, a wheel having an outwardlyldirected metal flange situated away from one side of the wheel the metal of the flange being however continued across the periphery of the wheel to such side and overlapping the side, the edge of the overlapping portion being shaped to form an eutwardlydirected lateral rib, a detachable side-ring whose inner edge beds against the aforesaid rib on the wheel-element and wh-ese outer edge provides a flange opposed to the lirstmentioned flange, a detachable rim engaged between the two flanges, and beltsfor securing the side-ring to'the wheel element so positioned that the securing thrust on the side-ring takes place at points between its lines of Contact with the rim and the rib on the wheel-element respectively, the rim being wide enough to hold the main body of the side-ring clear of the wheel-element, for the purpose set forth.

3, In a wheel and detachable rim the combination of, a wheel having fast upon it an outwardly-directed flange at one edge, a central detachable ring having its two edges turned outward away from the wheel and toward each other to provide flanges `one fac-4 the detachable rim between these two flanges and the pai-ts being so proportionedthat the side face of the side-ring is held off the side face of the wheel-element by the aforesaid rband by engagement of its flange with the l'iln, and bolts for securing the sidering-tov the wheel-element so positioned that the securing thi-ust on the side-ring takes' place at points between the lines of contzn-t with the i'iin and wheel-element respectively. for the piu-pose set forth.
